I have no words to describe just how amazingly epic this story is. Dark, and visceral and sad and desperate, but with such a serenely hopeful ending. Castiel's journey is heart-aching to watch unfold, and it made so glad to see him finally have the support he needed to start and overcome the hurt of his fall to humanity. I loved how his relationship with Risa managed to evolve into something wonderful after everything. And I LOVED the inclusion of Gabriel, and the fact that he fought for humanity - we saw he had great potential in the show, it was a shame Lucifer killed him. And Gabriel with Jo? That's just cool.
